30 weeks pregnant with severe pelvic pressure, lower back pain and a period like pain

Hi mummies!
I am currently 30 weeks pregnant with baby number 2 and i have had pelvic pressure for a while now. But it is getting to the point where it hurts when i roll over, put on pants, stand up after laying down, feels weird to wee and it is really starting to get me down I also have lower back pain and for the past 3 days been having a period like pain down low that comes and goes.. I'm thinking maybe braxton hicks? but didnt have them in my 1st pregnancy so dont really know! anyone else experience this??
